A man was rescued from his submerged pickup truck in Lunenburg Tuesday morning after the vehicle plunged into Lake Whalom, according to reports.

The Fitchburg Sentinel & Enterprise said two Lunenburg police officers dove into the water to rescue the driver, an unidentified man. Officers Deven O'Brien and Chuck Deming jumped into the water and, after initially being unable to open the truck's door, were forced to wait for enough water to enter the cab for pressure to equalize so the door could be opened.
